Perylene scarlet PR149 is a marginally lightfast, semiopaque, staining, dark valued, intense red pigment, offered by four pigment manufacturers worldwide. Unrated by the ASTM, my 2004 lightfastness tests give it a "very good" (II) rating; masstone and tint darken and dull after two months' exposure to sunlight.

Perylene scarlet PR149 is a marginally lightfast, semiopaque, staining, dark valued, intense red pigment, offered by four pigment manufacturers worldwide. Unrated by the ASTM, my 2004 lightfastness tests give it a "very good" (II) rating; masstone and tint darken and dull after two months' exposure to sunlight. Perylene derivatives are industrially important pigments used not only as colorants, but also as materials for optical disks and photoconductors for electrophotographic photoreceptors. These pigments cover a variety of shades in the solid state from vivid red, via maroon to black, although their molecular absorption spectra are quite similar in solution. The color generation mechanism has Toxicology Perylene pigments do not exhibit acute oral toxicity in animal trials, nor do they irritate the skin and mucous membranes. A 28-day (subacute) feeding trial carried out with a perylene pigment did not show any adverse toxicological results.

Perylene pigment

Perylene or perilene is a polycyclic aromatic hydrocarbon with the chemical formula C 20 H 12, occurring as a brown solid. It or its derivatives may be carcinogenic, and it is considered to be a hazardous pollutant. In cell membrane cytochemistry, perylene is used as a fluorescent lipid probe. It is the parent compound of a class of rylene dyes. Several perylene pigments have been developed for artist's paints : Pigment red 149, a middle red, between light and dark cadmium red.

2016-06-07 · Perylene “green” is not a green but a black pigment with a green hue. Like most black pigments it is obtained by combustion, in this case burning a derivative of perylenetetracarboxylic, i.e. another Perylene. This is a bit of a mouthful and just means that like most blacks, it is made by burning some substance.

Ils permettent de produire de nombreuses nuances de rouge : clair (PR123), moyens (PR178, PR149) et sombres (PR179, PR189, PR190, PR224, PV29) ainsi qu'un noir (PBk31, PBk32). Ils sont appréciés pour leur transparence, mais sont onéreux. Perylen wird in Form von Derivaten wie PTCDA oder MePTCDI als Pigment verwendet oder als Reinststoff in organischen Bauelementen wie Transistoren, OLED oder organischen Solarzellen. Weitere Derivate von Perylen wie beispielsweise Diindenoperylen (DIP) oder Dibenzo { [ f,f ′]-4,4′,7,7′-tetraphenyl}diindeno [1,2,3- cd :1′,2′,3′- lm ]perylen (DBP) und Les pérylènes sont des pigments organiques de synthèse. Ils peuvent produire beaucoup de nuances de rouge: claire PR123, signifie PR178, PR149, et sombre, et un noir PBk31, PBk32. Ils sont appréciés pour leur transparence, mais ils sont coûteux.

Perylenetetracarboxylic dianhydride (PTCDA) is an organic dye molecule and an organic semiconductor. It is used as a precursor to a class of molecules known as Rylene dyes, which are useful as pigments and dyes. It is a dark red solid with low solubility in aromatic solvents. The compound has attracted much interest as an organic semiconductor. Perylene scarlet PR149 is a marginally lightfast, semiopaque, staining, dark valued, intense red pigment, offered by four pigment manufacturers worldwide.
